JOSEPH N. FOUNTAIN, OF WESTFIEIIIVD MASSACHUSETTS, ASSIGEOR TO OLDCOLONY ENVELOPE COMPANY, OEWESTFIELD, MASSACHUSETTS, A CORPORATION OFMAS- DECKLING ivrncnmn;

" Ap ea -i... filed. August, 19, 1925. Serial No. 1,256.

This invention relates to improvements in 5 paper, card, bristol board,or the like.

It is commonrpractice to deckle the edges of paper during themanufacture thereof but this entails considerable expense in themanufacturing cost, and tends to retard the speed of production of thepaper. Finished paper has also been deckled by various means, moreparticularly, as by agrinding wheel but this method is'objectionablesince the grinding action tends to rapidly wear the wheel which thenceases to give the desired deckled appearance that corresponds to the:deckle produced in the manufacture of the paper.

According to my invention I am able to produce the desired results by"the provision of rotary cutting tools of novel form that are sodisposed with'respect to the edge of the paper that they act upon thepaper with a shearing cut and tend, during the cutting action, to exerta pulling strain upon the paper in opposite. directions.

7 I have found that various grades or kinds of paper require differentdeckled effects and according to one feature of the invention, I haveprovided a cutting tool holder that is adjustable so that according tothe tool v employed, it may be adjusted to position the axis of the toolso that it will operate on the paper with the desired, shearing andpulling action. v I

Other novel features will be apparent from the following description ofthe invention which, in the form at present preferred, is illustrated bymeansof the. accompanying drawings in which Y. I V

Fig. 1 is a plan View of the machine .7 Fig. 2 is a sectionalelevationalviewtaken on the line 2 2 of Fig. 1, showing the cutting tool.holder and driving means therefor V Fig. '3 is a sectional elevationalview taken on the line 33 of Fig.1, showing the cutting tool and supportfor the web of paper.

In describing'the novel features of my invention, it will be understoodthat the ma chine may be adaptedifor use with other material than paperor cardboard and that any reference to such material is only intended toassist in an explanation and an under-' stand ng Of 'the structure.

A table 1 for supporting a web of material such as paper, is providedthat is inthe form ofa flat plate member secured to and supported bystandards or legs 2. Guides 3, forguidinga web of paper through themachine, preferably, consist of flat plates disane;

posed ina, vertical position-and are guided on the table by tongues orslides 4. fitting between guideways 5 secured to the table,

These guides are movable Qtowards and away from one another and'are held1n various positions of adjustment by clam-ping screws 6. The-standardsor legs 2 are held in a rigid spaced relation by suitable tie rods7 andpreferably extend forwardly of-the supporting plate and havesecuredthereto cross bars 7' on which are fixed a plurality-of spaced bars 8and side guides 8 which form a receiving table for the sheets as theyare fed from the feed, table and through the deckling mechanism soon tobe described. This table may, of course,-'take any form desired and ispreferably arranged to incline downwardly from the table 1.

Shafts 9 and 9', rotatable in suitable bearings 10 of the supports2,'have fixed thereon coacting feed rolls 11 and intermeshing gears 12.The shaft 9 is provided with a driving pulley 13 whereb a rotary motion,imparted to the pulley, wi ljcause the rolls to operate in unison togrip therebetweena sheet or web of paper and feed it forwardly throughthe deckling mechanism and onto the delivery table. The pulley1'13 bedriven from any suitable source of 'power and at. any

speed desired or'lit may be belted to any of the well knownvariablespeeddriving devices so that the speed may be varied from timefto time.

Arod 14 extends across thejtable which is d r 95 supported in brackets15and carries a plurality oflfriction devices,',preferably in the form ofbrushes .16, which are adapted to bear upon the paper as it is fedforwardly by the feed rolls11 and tends to maintain the paperrin a'lflatcondition. Guide members l'l'fixed to the rodltextend forwardly thereofand have their forward ends'disposed beneath other-guidesr18 fixedtothe,

These 'guidesfa-re preferably ar-' guides '3. ranged to guide thepaperj'as it lsjfed' foracted upon 'by the cutting mechanism. I

I 'wardly and to vprevent' it. buckling when Silpp rt n -p at s are se ued at ther end in screw threaded engagement with the post 22 by themeansof which the tool hold er may be raised or lowered to various positionsof adjustment. An index dial 28 fixed on the screw carries designatingmarkings which may be registered with a pointer 29-located in an opening30 in the side of the standard by the means of which, settings of theholder may be duplicated as may bedesired. I

The holder '23 has av shaft 24 rotatable therein that is provided with atool holding chuck 25 of usual form at its forward end and a drivingpinion 2'6 fixed to its rearward end. A motor M atop of the holder has adriving gear 27 fixed to the shaft thereof that is in meshing engagementwith the pinion 26 for. driving the shaft 24".

A tool T preferably in the form of a milling'cutter having peripheralcutting teeth disposed longitudinally thereof, is clamped in the chuck25 and is preferably disposed so as to overlie apaper supporting member29" that is carried byan arm 30 extending upwardly from the'standard 21.This mem ber 29is arranged to engage the underside of the paper tosupport the same against the action of the cutter and may take any formdesired, that shown being a disc that is secured to the arm by a screw31. It is not necessarily rotatable on the screw '31v but may be fixedrigidly and moved about its axis to present new supporting surfacesshould the tool cut or injure it.

The cutting teeth of the cutting tool may take any of the usual forms,thatishown being of the spiral type which has been found preferable forcertain kinds of paper, while straight teeth or nearly so, may be moreadvantageously employed for other kinds.

As will be'noted, the tool holder may be adjusted vertically toaccommodate different thicknesses of paper. or to create various deckleeffects and that it is rotatable so that according to the type of toolemployech'the tool may be disposed at various angles with respect to theedges of thepaper whereby it will operate thereagainst with a shearingaction as is desirable to produce the most perfectdeckle edge effect.

Regardless of theparticular form of cutting tools employed,'it is.possibleto so position them with respect to the edge of the paper thattheir cutting teeth will, when operating on the paper, exert a pullingaction,that is, while the cutters are'acting upon opposite edges of thepaper they will also tend topull the paper in opposite di- Ti rectionsto flatten the paper for the shearing cut and thereby assist the cuttingoperation so that the finest possible cuts may be made to produce thedesired fine quality deckle edge.
